摘要： In a variable valve actuation system of an internal combustion engine employing a variable valve actuator capable of variably adjusting at least intake valve closure timing depending on engine operating conditions, a processor of a control unit is programmed to phase-advance the intake valve closure timing to a predetermined timing value after a piston top dead center position and before a piston bottom dead center position on intake stroke during at least one of an engine starting period and an engine stopping period. The variable valve actuator includes a biasing device by which the intake valve closure timing is permanently biased toward the predetermined timing value.

摘要： A rocker arm which supporting a free cam follower is rotatably supported by an engine-cylinder-mounted rocker shaft to lift cylinder valves against valve springs. The rocker arm and the free cam follower are in cooperation with first and second cams on a camshaft. A lever is supported by the rocker arm and has a locked position wherein the lever is in driving engagement with the free cam follower to provide a positive motion connection between the free cam follower and the rocker arm and a released position wherein the lever is out of driving engagement with the free cam follower to provide relative motion of the free cam follower to the rocker arm. A hydraulic piston and a release spring cooperate with each other to shift the lever between the locked position and the released position. For adjusting the shifting operation in timed relationship with motion of the rocker arm, a latch is arranged to restrain motion of the hydraulic piston when the rocker arm is unlifted and until the rocker arm is lifted.
